Carrier 38HDL024 Defrost Sensor Board
The defrost control board is jobbed with determining when to begin the defrost cycle which actually helps to continue normal heating and cooling operations. It depends on a defrost sensor that can be found near the condenser, in order to decide when to initiate the defrosting cycle.
What to see if the defrost sensor board is failing?
- The control board could signify a type of error code produced by a bad defrost control board
- Self defrost sequence never kicks in even though there is quite a bit frost that needs to be removed
- The AC may stop working at all because of way too much frost build-up
